Camera collision detection?

Unity Engine
1

I want to make my camera move at the ball when the camera has a object in between it, or is in a wall and back when there isnt for example ( atleast when between).

How would I go about doing this I have been trying to figure it out XD

I have the balls camera at a angle aiming down at it so I assume I need to use local position to make it move at the angle i want (its faceing ( currently at the ball)

I was also puzzled on how to figure out what the object is that is hit by a ray (new to rays)

Easy, you use a Physics.Raycast from the player to the camera. If it hits something, then you subtract 1 unit for measure and place your camera there.

var ray : Ray=Ray(target.position, target.position - transform.position);
var hit : RaycastHit;
if(Physics.Raycast(ray, hit))
transform.position=ray.GetPoint(hit.distance-1);

what is the target in target.position ?

I have it like this

var player = GameObject;

function Update () {

	var ray : Ray = Ray(player.Transform.Position, player.Transform.Position - transform.Position);
	var hit : RaycastHit;
	
	if(Physics.Raycast(ray, hit)){
		Camera.main.transform.position = ray.GetPoint(hit.distance-1);
		
	}
}

However on line 6 i have problems with the player which will be the ball and the commands to get his position to start the ray and to send it to the camera script attached to I tried lots combos of what commands put after the player but doesnt work …

Does anyone know why the

var ray : Ray = Ray(player.Transform.Position, player.Transform.Position - transform.Position);

does not work, errors with red mark on left in editor ?
